DISPENSER FOR PULVERULENT AND PASTY SUBSTANCES J Filed Aug. l4, 1929 2 Sheetsheet 2 Patented Nov. 1?, 1931 JOSEPH EUGENE BAPTISTE MAILLAED, 015 NOGENT-LE ROY, FRANCE DISPENSER FOR PULVERUTIEK'T AND PASTY SUBSTANCES Application filed August 14, 1929, Serial No. 385,766pand in France August 14, 1928.

This invention relates to a dispenser or distributor suitable for pulverulent and pasty products of all kinds such as face powder, rouge, soaps in powder or paste, tooth powders, talc and other materials.

Apparatus constructed for this purpose usually comprises a receptacle from which the product issues, a perforated top on the receptacle and a spring-pressed piston for discharging the product. Charging the apparatus is a rather complicated matter, and in the case of rice powder for example, a certain amount slips round behind the piston. Moreover, in the case of powder puff boxes the 15 powder tends to collect towards the periphery of the box and to be scattered by the powder-puff. I

If the powder issues in excess, it is practie cally impossible to return it to the interior of the box. The powder issues through the perforations in a finely divided condition, and its adhesion to the powder puff is reduced,'so that some of it drops off onto the clothing.

One of the objects of the present invention is to obviate these inconveniences.

By way of example, constructional forms of distributor embodying the foregoing and other features of the invention are illustrat-v ed in the accompanying drawings.

The illustrative embodiment of the invention shown in Figs. 1 to 7 comprises'a case or box provided with a lower compartment 1, in the bottom of which turns a gear wheel having a hub 3 and pivot pin 4, the spokes 5 of said wheel being curved with the concave side facing the direction, of rotation. A worm conveyor 6, is mounted on a shaft 7, 7 Figs. 1 and 2, said "shaft also carrying a knob 8 for actuating the conveyor anda pinion 9 meshing with and transmitting movement to the aforesaid wheel 2 when the shaft is rotated by means of the knob 8.-

The inner end of the shaft 7 is journaled' in a plate 11 forming the inner end-wall of a container or casing 10 enclosing the worm conveyor 6. One side wall 12 of the casing 10 is cut away at 141, see Fig. 6, to enable the spokes 5 to feed the powder in the coinpartment 1 to the conveyor within the casing. The opposite side wall 13 of said cas-" ing is provided with a cut away portion 15, see Fig. 7, in front of which is disposed a retaining plate 16. There is sufficient clearance below the plates 11, 13 and 16 to allow the spokes 5 of the wheel2 to pass. Said 7 plate 16 is secured by screws 20 to the side plate 13 and to said plate'16 are secured flex ible strips or teeth 17 of spring steel or rubher for example, said flexible strips being held in position between said plate 1'6 and a counter plate 18 by screws 19. Thefiexible strips or teeth 17 extend downwardly into the path of movement of the spokes 5 of the wheel 2,.said strips or teeth yielding to give passage to said spokes but tending to prevent passage of the powder which is thus retained in proximity to the worm conveyor which is thus always assured a supply of powder-to be fed or conveyed thereby.

, Directly above the worm conveyor 6 in the center of the compartment 1, is a small platform 21 which may conveniently be faced with smooth velvet or'leather 22 and which is provided with adischarge port 23. through which the powder can be dis charged by operation of the conveyor: The platform 21 is supported and attached to the body of the container 1 by arms 24, of a spider 2, see Fig. ,4. A closure is provlded for the discharge port 23, said closure herein comprising a sliding plate 26 provided with an opening 27 and carried by a rod 28 which slides in a guide 29 on an arm 25, the'free end of said rod projecting outwardly through tie container wall.

The lid or cover 33 is hinged atAlQ, see Fig. 3, to the lower container 1. When the box is closed a spiral spring 30, which en'- circles the rod 28 between the guide 29 and a shoulder 31 on said rod, see Fig. l, tends to push said rod toward the left, viewing Fig. 3, the end of the rod thus pressing against the inside'of'thc rim 32 of the lid 11G lid is fastened in closed position by a spring catch 35'controlled by a push knob 8d, the free end 360% the spring catch 35 engaging in a recess inthe ri1n- 3:2,and in. this position, the discharge port 23 isclosed by the solid portion of the sliding plate 26.

On pressure being'applied to the knob 3d, the catch recedesand releases the lid 33, which opens automatically in response to the pressure exerted by the end of the rod 28 on the rim. 32 of the/lid, under action of the spring 30. The rod 28 and attached sliding plate 26 arethu'smoved to the left, viewing 3 Fig. 3, and'th'e discharge port or opening 27 in said sliding plate 26 then registers with thedischarge' opening 23 inthe platform 21,

thus permitting'the powder in the casing'lO to escape on being subjected to the thrust of the-worm conveyor 6.

rrremovable disk 37, which rests upon the platform 21 is provided with a central opening 38"preferahlyof a-slightly smaller diameter'than'- that of'sa-i'd platform, said opening 38 registering with the opening 23 in said as-extendingthroughout the full diameter of the container 1. The vanes of the conveyor at opposite sides of the center of the shaft 7 are oppositely wound. the construction and arrangement being such that as the conveyor is rotated the two worms will feed the powder from opposite directions to the central dis charge port 23. The conveyor casing 10' also extendsthroughout the full width of the container and is provided with" duplicates of the construction shown'in Figs. 5. .6 and '1'. as will be readily lmderstood-by those skilled in the art witl iout' further description.

In operation the disk 37 having been removed. thecompartment 1 charged with powder and the disk replaced, the lid 33 will be in the plate 26 will be brought into registration with the discharge port 23 and the cen tral opening in the disk. 371 If now he knob :23 be turned in a clockwise direction, 'iewing said knob from the right of Figsl and 8, the shalt? through the pinion 9 ant gear teeth on the wheel 2 will cause said wheel to rotate in a clockwise directiom viewing 2 and 8..andthe arms 5 will feed the powder in the contain 1' 1 to the worm 6 in the casing 10, the ii. teeth 1? retaining the powder within tne casing within reach of. the con-- Yeyorwhile permitting the spokes 5 to pass freely. Rotation of the knob 8 also produces rotation of the worm G which thus feeds the powder from the container 1 and discharges it to the dischargeport 23, Where it is avaiL able: for use by'means-of the puit or pad rostlHfI'OE']. the dish 37' or in 21113 other suitable manner;

It will: be understood that the several om bodiments are given merely by way of example. and that theyinay bevaried without departingfrom the scope of: the invention. it will also be understood: that any suitable materials for example metals, wood. plastic materials and cardboard, may be employed in malr' ig the various parts described.
